Build a range of Android applications that address common real-world issues such as authentication, connecting to synchronous and asynchronous remote sources, rendering complex UIs with Jetpack Compose, and more with Google Developer Expert, Gema Socorro RodriguezKey FeaturesGet hands on with Android development by solving challenging real-world problems and developing three practical projectsUse the latest features of libraries in Jetpack Compose, Room, CameraX, ExoPlayer, and moreLearn best practices for UI creation, app structure, data handling, and lifecycle management in AndroidPurchase of the print or Kindle book includes a free PDF eBookBook DescriptionFinding resources on creating apps with the Android framework and Kotlin is easy, but discovering content that addresses the common challenges faced by app developers is difficult. This book is designed to bridge that gap and equip you with the skills to tackle everyday problems in Android development.

You'll get hands on with Android development by building an app similar to WhatsApp. Next, you'll learn how to process asynchronous messages reactively, render them using Jetpack Compose, and advance to creating and uploading a backup of these messages.

As you progress, you'll develop Packtagram, an app inspired by Instagram, focused on advanced photo-editing capabilities using the latest CameraX libraries. Finally, you'll build your own Netflix-like app, integrating video playback functionality with ExoPlayer for both foreground and background operations, and enabling casting to other devices.

By the end of this book, you'll have crafted three fully functional projects across multiple platforms and gained the expertise to solve the most common challenges in Android development confidently. What you will learnCreate complex UIs with Jetpack ComposeStructure and modularize apps with a focus on further scalingConnect your app to synchronous and asynchronous remote sourcesStore and cache information and manage the lifecycle of this dataExecute periodic tasks using WorkManagerCapture and edit photos and videos using CameraXAuthenticate your users securelyPlay videos in the foreground and background and cast them to other devicesWho this book is forIf you're a mid-level Android engineer, this book is for you as it will not only teach you how to solve issues that occur in real-world apps but also benefit you in your day-to-day work.

This book will also help junior engineers who want to get exposed to complex problems and explore best practices to solve them. A basic understanding of Android and Kotlin concepts such as views, activities, lifecycle, and Kotlin coroutines will be useful to get the most out of this book.
